Why do I still feel wrong?

I was seeing two people. I wasn't officially together with either of them. It was with my daughters father and my long time friend. I decided that my ex was never going to treat me the way i need. So I told him I wanted to see someone else. But I don't feel good about telling him or about being with the other guy. I feel like I am not winning with either guy but I love them both to death. The guy I am with is really good to me & we get along so well. Though I still feel wrong and conflicted. Advice please?
